Hi Guys. I'm 6ft 2" so fitting in my car is a challenge. I do not want Gurney bubbles and I need to wear a helmet. Thus I positioned the base of the carbon seal 2mm from the allow floor. This required me to custom position seat mounting points in the seats and also customise mounts as per below.
Mounts were bonded into the seats before the inner and outer shells were assembled. I then customised alloy mounts and machined alloy washers to lock the seats in securely. Seat above is shown before I polished them. Below seat has not been trimmed yet and I had not fitted the belt protection in the seat openings yet. I then made small leather headrests over a fiberglass form with thin rubber padding to protect my helmet.
The back of the seats are 3mm from the rear roll bar so that I can fix a small rubber pad to the bar and the cage will take full load in the event of a shunt from the rear. The seats should be strong enough but the bar is there so I used it.
I have added the second bar like Tom and used a micro-slip three bar plate to wrap the shoulder belts. This ensures the 20deg angle is achieved and no adjusters foul with the seat or my shoulders.
Its all a very tight fit but the result is great. By angling the seats I can fit in the car with a very low seating position that is comfortable. Because I have long legs the seat base angle suits me as my knees sit up anyway with the pedals pushed far into the foot well on a custom milled adjustable plate. The seat is fixed and the pedals and wheel move. If you are short this installation will not suit as it may push your knees up too high and you will not reach the pedals. If you need dimensions just ask what you want and I can measure it. I have also got a set of leather traditional seats that fit the same mounting points for road driving without a helmet (I sit higher in these).
Julian at about 5ft tall this is how your seating position will be!!!! This would also be Fran's seating postion
Notice the braking difficulty and issues with 1st, 3rd and 5th gear engagement depending on your transaxle!
You can see the concern with the setup from this young test pilot!
By the way this is not my GT40, I am told by my daughter below that it is
HER GT40!
